HYDROCARBON-FURNACE.

SPECIFICATION forming part of Letters Patent No. 306,934, dated October 21, 1884.

application filed February 2, 1884. (X model.)

To all whom it may concern:

Be it known thatI, ALLEN N. LEET, a citizen of the United States, residing at N cwark, in the countyof Essex and State of New Jersey,

have invented new and useful Improvements in Hydroearbon-Furnaces, otwhich the following is a specification.

It is often desirable to use petroleum or hydrocarbon liquid as the source of heat in a steam-generator, as it is wellknown such liquids produce an intense heat on combustion, and are at the same time among the most economieal sources of heat available for the purpose. Many devices have been proposed for the purpose, usually quite complicated, and precluding the use ofany other source of heat. It also seems desirable, therefore, th at some means should be provided for utilizing hydrocarbon liquids as the combustible under sleanrgenerators which should not require any change in the construction of the ordinary combustionchamber, but which can at will be placed therein for use or withdrawn therefrom.

The object of my invention is to provide such means; to which end it consists in the combination of devices more particularly hereinafter set forth and claimed.

In the drawings, Figure 1 represents a 1011- git-ndinal vertical section. Fig.2 is a horizontal section in the plane .r as, Fig. 1.

Similar-letters indicate corresponding parts.

In the drawings, the letter A designates the furnace-wall, which supports the firegrate 13, to which access can be had througha door, and beneath which is the ordinary ash-pit, which is open, so that the atmosphcricair can pass freely intoiit. On the grate is placed a pan, 0, of iron or any other suitable material, and this pan is supplied with petroleum-or other hydrocarbon liquid through a pipe, D, which extends from a tank, E. The supply of hydrocarbon liquid is regulated by a stopcock, a. The pipe D is by preference made to extend down near to the bottom of the pan, .5 so that the flame is not liableto pass into said pipe.

In front of the pan 0 is situated a tubular head, F, which is provided with a series of nozzles, b, which may rest upon the edge of the pan, as shown, so that they sustain the head F, or which may be arranged in any other manner, so that jets of steam injected through them will sweep over the surface of the liquid contained in the pan. The headF connects, by means of apipe, G, with asteamgenerator, H, and this pipe is provided with a stop-cock, 0, so that the supply 0t steam to the head F and nozzles 12 can be regulated. This head F, being of larger section and ca pacity than the supply-pipe, furnishes a oham- 6Q ber in which the pressure ofthe steam is equalized, so that it may issue from all the nozzles with equal and controllable force.

If the furnace is to be used for a steam-boiler, an additional steam-pipe must be provided, 6 which connects with a supplementary steamgenerator, and which supplies steam until the boiler H has been heated to the required tem perature to produce steam. When the pan 0 has been supplied with a sufficient quantity of hydrocarbon liquid, this liquid is ignited, and then the steam-pipe G- is opened. By means of the jets of steam the flame of the hydrocarbon liquid is spread, a large quantity of atmospheric air is caused to rush in from below, and the flame becomes very powerful and intensive, so that a great heat is produced with a comparatively small expenditure of fuel.

It will be noticed that the use of these devices necessitates no change in the combustion or s tire chamber,it remaining unchanged and ready for use with other combustibles when desired.

To use this device it is simply necessary to set the pan upon the gratebars and make the 8 pipe-connections D and G, while to use coal or other combustible it is simply necessary to remove the pan and unscrew the pipes D and G at the cocks a and c or other convenient pointsthe work of but a moment, not requiro ing any amount of technical skill nor the aid of tools beyond a mere wrench.

Vhat I claim as new, and desire to secure by Letters Patent, is v 1. The combination, with the furnace-grate, 5

of an open pan adapted to be placed therein, a pipe leading into the pan and connecting it with a tank or supply of hydrocarbon liquid, a tubular head situated in close proximity and parallel to the pan, and of larger capacity r00 than its supply-pipe, a series of nozzles projecting therefrom, and a pipe connecting the liquid in. the pan, the whole forming a .retulily removable or replaeez'thle device for burning hydrocarbons under furnaces, substantially as I 5 deseri bed.

In testimony whereof I have hereunto set my tubular head to a source or supply of steam, substantial] y as described.

2. The combination, with a l'urnaee-grate,of

an open pan seated or placed on the grate and 5 adapted to contain a hydrocarbon liquid for ing witnesses.

imity to and parallel to the pan a pipe connecting this head to a supply 01' source ofsteam, and a series of nozzles projecting from said 10 head and resting upon the edge of the pan, whereby the tubular head is supported and jets of steam forced over the surface of the ALLEN N. LEET. [L
